Abstract

Kalangan Hamlet is one of the coastal communities in Pahawang Island Village, Lampung. It has abundant natural resources and offers prospects as a tourist destination. It is located away from Pahawang Island, so the area is considerably behind in terms of tourism management. The aim of the research was to develop effective strategies for managing the coastal areas of Kalangan Hamlet. The strategies had been suggested to contribute to Kalangan Hamlet's potential for coastal tourism growth. Data was collected using survey and observation methods, with respondents chosen through the snowball sampling technique. The collected data was analyzed using Strengths, Weakness, Opportunities, and Thread (SWOT) analysis and Analytic Hierarchy Process (AHP). The primary strategy for managing the coastal areas of Kalangan Hamlet involves enhancing infrastructure to support tourism, while simultaneously prioritizing the preservation of the natural ecosystem and ensuring the well-being of the local population. This approach balances economic development with environmental sustainability and social equity, thereby fostering a holistic and sustainable tourism model.

Abstract

A booklet is a combination of a leaflet and a small book so it is practical and can be used as a guide. The aim of the research is to develop a booklet on pests and diseases of crystal guava as well as online-based management methods. Pest and disease booklets need to be developed considering that pests and diseases are the main obstacles to agricultural productivity, disrupting plant physiology and growth so that they can reduce crop yields. Data collection was carried out through observing samples of crystal guava plants, as well as interviews with owners and managers to obtain information about pests and diseases of crystal guava. Data was analyzed descriptively qualitatively. The results of the research found 4 crystal guava pests, namely: codot (Cynopterus spp.), ladybugs (Epilachna admirabilis), fruit flies (Bactrocera dorsalis), and mealybugs (Paracoccus marginatus). The diseases found were the fungus Capnodium citri (sooty dew), algae (Chephaleuros virescens), fungus (Festlotiopsis psidii), and nutrient deficiencies (potassium/magnesium). Crystal guava is cared for by keeping the garden clean, spacing the plants, applying fertilizer, spraying insecticide, installing fruit fly traps, and wrapping the young fruit. The research output is in the form of a booklet, then converted into a video and uploaded to YouTube at the link: https://youtu.be/9bzldxynnl3q. This research still needs to be carried out in two seasons, namely dry and rainy, so that it can produce more types of pests and diseases, so that the online booklet results are more optimal.

Abstract

Hypertension is a risk factor that contributes to the development of stroke, heart failure, myocardial infarction and kidney failure. Even though in some cases the symptoms can be found, there are quite a few who think of it as just an ordinary disorder so they realize too late that hypertension is affected. This study aims to determine the effectiveness of giving honey in reducing blood pressure in elderly people with hypertension at the Theodora Makassar Nursing Home. This type of research is experimental with a cross-sectional design. The sampling technique was purposive sampling for 7 research subjects. Data was collected through primary data measuring blood pressure before and after administering forest honey with and/or without antihypertensive medication. The statistical test used is the paired T test. The results showed that the average systolic blood pressure before giving honey was 143.28 mmHg and after giving honey 134.14 mmHg. Then the diastolic blood pressure before honey was 82.14 mmHg and after honey 71.85 mmHg. The average systolic and diastolic blood pressure after administering honey was 134.14 mmHg and 71.85 mmHg. The statistical test results obtained a p-value of 0.018 for systolic blood pressure and a p-value of 0.011 for diastolic blood pressure (p<0.05). The conclusion is that giving honey is effective in reducing blood pressure in elderly people suffering from hypertension at the Theodora Makassar Nursing Home.

Abstract

Pteridophyta ferns are a group of vascular plants that have a very long evolutionary history. This study aims to describe the relationship of terrestrial fern plant species (Pteridophyta) at Salodik Waterfall Central Sulawesi based on morphological characteristics. The method used was exploration method with the sampling technique being free collection. The data were processed using Microsoft Excel 2013 and then subjected to cluster analysis using the UPGMA (Unweighted Pair-Group Method with Arithmetic Average) method in the PAST 4.03 software (Paleontological Statistics). The research results obtained a total of 13 terrestrial fern plant species, namely Asplenium nidus, Diplazium esculentum, Davallia denticulata, Lindsaea scandens var. terrestris, Nephrolepis biserrata, Angiopteris evecta, Phymatosorus longissima, Pteris biaurita, Pteris fauriei, Selaginella doederleinii, Chingia clavipilosa, Macrothelypteris torresiana and Sphaerostephanos heterocarpus. The dendrogram of kinship between 13 species of terrestrial ferns is formed in 2 main clusters with 4 relationships categories, namely very near, near, not near, and not very near. The first category of relationship is very near with the highest Similarity Index (IS) value, namely between Macrothelypteris torresiana with Davalia denticulata (IS=86.5) and Lindsaea scandens with Pteris faurei (IS=75.2). The second category of near relationship is between Pteris biaurita with node 3 (IS=68.2), Selaginella doederleinii with node 4 (IS=64), and Diplazium esculentum with Chingia clavipilosa (IS=55.6). The third category of not near relationship is between Nephrolepis biserrata with Phymatosorus longissima (IS=27.3). The fourth category of not very near relationship with the lowest Similarity Index (IS) value is between Angiopteris evecta with Sphaerostephanos heterocarpus (IS=22.8) and Asplenium nidus with sub division Ia (IS=21.2).

Abstract

Food problems are a very serious topic globally. This does not only include basic food ingredients such as grains, tubers or other substitute ingredients, but also includes the need for supporting ingredients such as fruit. One of the fruit commodities that many people need is melon (Cucumis melo L.). The availability of melons on the market is currently dominated by farmers' seasonal crops, so their availability is relatively limited outside the season and a surplus during the season, so this has an impact on price stability, both for farmers and consumers. One method that can be offered for this problem is how to carry out cultivation that is not tied to the season by using a greenhouse combined with hydroponic or conventional drip irrigation cultivation methods. The results show that the use of hydroponic methods and drip irrigation can stimulate the growth and especially the development of melon plants. The appearance of flowers in the hydroponic system starts at 2-3 WAP, while in the drip irrigation system it starts at 3-4 WAP. The emergence of productive branches in both methods also takes place from the age of 2 WAP and continues to grow. So from several aspects such as optimal growth, long-term cost efficiency, sustainable agriculture and efficient use of water for agriculture, these two methods can be an effective alternative for melon cultivation.

Abstract

Diabetes mellitus is a serious long-term (or 'chronic') condition caused by increased levels of glucose in the blood because the body cannot produce one or enough of the insulin hormones, or cannot use the insulin it produces effectively. IDF data, the global prevalence of DM in 2019 is estimated at 9.3% (463 million people), increasing to 10.2% (578 million) in 2030 and 10.9% (700 million) in 2045 (IDF, 2019). Research results (Riskesdas) in 2018, the prevalence of diabetes mellitus in South Sulawesi diagnosed by doctors was 1.8% and 1.3%. WHR is a method for assessing fat accumulation in the body. The risk of DM is more related to intra-abdominal fat than subcutaneous fat. WHR was shown to be a better predictor of type 2 DM risk compared with BMI. The WHR limit for men in Asia Pacific is >0.9 and women >0.85. To determine the relationship between RLPP and fasting blood glucose levels in type 2 diabetes mellitus patients at the Tabarringan Community Health Center. This research is an analytical study using the Cross Sectional method, to determine the relationship between Fasting Blood Glucose and Waist-Hip Ratio. The research results showed that from 65 respondents a p-value was obtained of 0.514 > 0.05 so that Hnull was accepted and H1 was rejected. So the results obtained are that there is no relationship between WHR and fasting blood sugar levels. There is no relationship between WHR and fasting blood glucose levels in type 2 diabetes mellitus patients at the Tabarringan Community Health Center.

Abstract

Mangroves are typical plants that live in coastal areas that are affected by tides and are able to adapt to salinity. Mangroves are able to absorb and store carbon. The aims of this study to analyze carbon absorption in the mangrove vegetation of Sumbernadi Village. The research was conducted from June-July 2023 in Sumbernadi Village, Ketapang District, South Lampung, Province of Lampung. Mangrove carbon measurements in mangrove stands, necromass and litter were carried out using non-destructive methods. The carbon stored in sediment is greater than carbon stored in stands, necromass and litter. The highest carbon stored in sediment is in sediment that has coarse clay because coarse clay can store high levels of nutrients.
